Re: [Elecraft] KPA500 Attenuation in Operate

Ok...here is the solution, Craig at Elecraft immediately suggested I check R7 
on the LPF board. Good suggestion since it was missing...he is sending me R7 
smt which should fix the problem.

I really don't understand your comments since there is no tuner in the KPA500

I too, see this in my shack.  For example, tuner is on automatic, last tranmit 
band was 20mtrs, and I listen to 40 mtrs...signal way down.  Transmit, the 
tuner tunes, and the signal strength is normal.

If you have your K3 connected to the tuner to supply frequency info to the 
tuner, and you have "trained" the tuner to preset tuning for frequencies you 
use, this should not happen.

In my case I am using a Flex6700 with the tuner...freq info not sent to the 
tuner, so this is common for me.
